A minimal axion model for mass matrices with five texture-zeros
Yithsbey Giraldo, R. Martínez, Eduardo Rojas +1
A model with fermion and scalar fields charged under a Peccei-Queen~(PQ) symmetry is proposed. The PQ charges are chosen in such a way that they can reproduce mass matrices with fi…
The OTELO survey: Revealing a population of low-luminosity current/active star-forming galaxies at z
Rocío Navarro Martínez, Ana María Pérez-García, Ricardo Pérez-Martínez +16
We study a sample of H emission line sources at 0.9 to identify the star-forming (SF) galaxies sample and characterise them in terms of line luminosity, stellar mass, SFR…
Radiative seesaw-type mechanism of quark masses in SU(3\)_{C}\otimes SU(3\)_{L}\otimes U\(1\)_{X}$
A. E. Cárcamo Hernández, R. Mart'\inez, F. Ochoa
We take up again the study of the mass spectrum of the quark sector in a model with gauge symmetry (331). In a special type II-like 331…
Neutrino masses in a 331 model with right-handed neutrinos without doubly charged Higgs
M. E. Cataño, R Martínez, F. Ochoa
We discuss a 331 model with three scalar triplets and neutral fermion singlets. We show that in the 331 model with right-handed neutrinos, it is possible to obtain small active neu…
Unitarity Constraints for the Mass of the Higgs in the Gauge Model
R. Martínez, N. Vanegas
The critical values for the mass of the Higgs bosons, at which the theory becomes strongly interacting, are calculated using the equivalence theorem, at high energies this allows u…
